DESIGN, MANUFACTURING, REPAIR

OPTIMEX is exclusively dedicated to conception, manufacturing, tests and after sales service of Canned Motor Pumps. Created in 1998, our company has been growing ever since, and has become a major actor in this field on the international market.

Used for dangerous, toxic and explosive liquids as well as for major and valuable processes, canned motor pumps are chosen for their robustness and reliability. They confer the highest safety level on the market thanks to its double hermetically sealed containment.

Among ohters we design and manufacture our pumps according to the following standards:

• ISO 2858, ISO15783, API685, directive 2006/42/EC (Electrical machinery) directive 94/9/CE (ATEX), EAC (Eurasian Conformity), CUTR (Customs Union Technical Regulations For Belarus, Kazakhstan and Russia), directive 97/23/EC (PED).

• OPTIMEX answers the quality management requirements established by ISO 9001 and NF EN 13980.

Remaining attentive to its international customers’ requirements, OPTIMEX adapts its production to local Ex-proof directives (ATEX, CUTR, UL, CSA).

Needs for high Total Discharge Head (TDH) require the use of Multi-stage pumps. OPTIMEX focused on developing a range of products that would fit all requirements from the Chemical, the Energy and the Oil & Gas industries’ requirements. Even if the API685 does not cover this kind of pumps, OPTIMEX respects, on demand, all its applicable paragraphs.

Now recognized for its imposing achievements for critical applications (such as liquefied gas), OPTIMEX is strongly appreciated for its skills and know-how.

Each OPTIMEX pump is identified by a unique serial number (BFXXXX) and a complete designation name that reflects all its main characteristics (regarding hydraulic and motor selection, design specificities and main construction options).

STANDARD FLANGES RATING IS #300 IN ACCORDANCE WITH ASME B16.5.

+In accordance with the materials required by API685, OPTIMEX has made a standard selection that covers to its maximum your usual applications, in terms of liquid compatibility and operating temperature range.

SLIDE BEARINGS+

316L/GRAPHITE Slide bearings are one of the major parts that confer such a good reliability to seal-less pumps.

In mutli stages canned motor pumps, the monobloc shaft composed of all the rotating elements of the machine is supported by two types of slide bearings that are totally submersed in the pumped liquid:

A: The motor bearings: they are by 2 on every machine.

B: The intermediate bearings: their quantity is defined depending on the number of stages on the pump.

Once the pump’s filling is guaranteed (and controlled with the appropriate instrumentation), the pump can be started.

The mobile will rotate free from any friction and wearing, thanks to a thin film created by the pumped liquid ensuring the radial thrust.

316Ti/TUNGSTEN CARBIDE COATING/SIC30For critical applications with risks of dry running (frequent and delicate start-up or critical liquids for which full characteristics have been transmitted and approved by OPTIMEX), SIC30 bearings are advised and proposed.

Parts and composition are shown below.

In case of bearing capacity losses, friction between sleeve in SIC30 and specific coating on shaft sleeve is acceptable for small periods.

R2 Pumped liquid

Pumped liquid and motor liquid are identical and they slightly communicate in order to establish an equipressure between the 2 areas (high and low temperature). On the motor side the liquid circulates in an external heat exchanger, flow is established by an auxiliary impeller. A thermal barrier is built between the hydraulic casing and the motor (air or water).

R6 Pumped liquid

Injection in the motor from the hydraulic casing (at the impeller periphery), circulation through the gap, and return to the pump casing, between two impellers, via the hollow shaft. The process flow is discharged through a double casing around the motor, in order to evacuate the calories externally, and to complete the cooling of the internal circulation.

SR6 Pumped liquid

A part of the liquid called « process flow » is discharged through a double casing around the motor, in order to evacuate the calories externally, and to complete the cooling of the internal circulation. A second part of the liquid is injected in the motor from the hydraulic casing (via a auxiliary impeller), then circulates through the gap, and is re-injected to the process flow at the rear bearing support.

SR : COOLED OVERPRESSURED CIRCULATIONS

According to the operating conditions and fluid properties, OPTIMEX selects the appropriate circulation plan to optimize the functioning of the pump. See above our standard circulations for normal conditions, liquefied gas (pressurized), hot liquids (cooling loop) and liquids with particles (filtered). For critical applications, OPTIMEX can develop customized circulation plan to guarantee a good lubrication and cooling of the motor.

Over the years OPTIMEX has developed a performing and reliable thrust balancing system for its MULTI Range. It is one of the key factor that lead OPTIMEX to become a reference for designing such equipment. Indeed, the compensation of the radial forces implied by the large number of centrifugal impellers is essential to operate the MULTI pumps in good conditions with high reliability. OPTIMEX know how and experience gave the opportunity to design and manufacture some of the largest and imposing realizations on the market.

Each of the impellers, is partially self-balanced with a stable restriction orifice located at its rear 1 .

Still, it is not fully efficient and sufficient, and residual negative force pull the mobile to the suction side. Moreover the system must be dynamic to regulates the complete mobile’s position in function of the whole operating range.

To achieve a complete balancing, a piston 2 is used to create a variable gap 3 that regulates the pressure in the regulating chamber 4 .

If the mobile moves to the rear:

Gap is wide, and losses are low. As a consequence, regulating chamber’s pressure is high. Resultant of the force is negative, the mobile moves back to the front.

If the mobile moves to the front:

Gap is nearly closed. Regulating chamber’s pressure decrease down to lower pressure from an intermediary impeller through the hollow shaft 5 . Resultant is positive, the mobile moves back to the rear.

In the stable functioning phase, pressure in the chamber is regulated between high and low pressure. Resultant force is null and the mobile remain perfectly balanced without any friction.

Axial thrust balancing of every MUTLI pump is checked on the full operating range during performance test.
